minHeight property

double minHeight

The minimum height constraint to give the child. Set this to null (the default) to use the constraint from the parent instead.

Implementation 

double get minHeight => _minHeight;
void minHeight= (double value)

Implementation 

set minHeight(double value) {
  if (_minHeight == value)
    return;
  _minHeight = value;
  markNeedsLayout();
}
